IMPROVEMENT m LAMPS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, E. D. NORTON, of Bradford, in thecounty of McKean, and State of Pennsylvania, have invented a new and useful Improvement in Lamps; and that the following description, taken in connection with the accompanying drawings hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvements by which my invention may be distinguished from all others, of a similar class, together with s ch parts as I claim and desire to have secured to me by Letters Patent. I

The present invention consists in combining with lamps, such as are used more particularly for burning coal or other similar oils, :1. safety-valve of a novel construction, through which the gases formed upon the interior of the lamp can escape as fast as generated, and thus all possibility of an explosion be obviated. In the accompanying plate of drawings my improvement in lamps is illustratedt Figure 1 being a side view of the body or oil receptacle to the lamp, with the safety-valve in central vertical section, and I I Figure 2 a section in the plane of the line .1; x, fig. 1.- v v A, in the drawings, represents the body or oil receptacle of the lamp, having applied to one side a screwcap, B, in which my improved safetywalve O is arranged. This valve 0 consists of a tube, D, arranged to play through the cap, moving by its slot a upon a pin Z), thereof. This tube D is closed at its outer end, and in its side is an opening, E, covered with a wire gauze or'netting, F, this opening being located at or near the closed end of the tube.

By the safety-valve above described, when there is any pressure of gas upon the inside of the lamp it is raised, and thus through its opening E, which then comes upon the outside of the screw-cap, the gas is allowed a free escape, as is obvious without any further explanation.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent- A safety-valve constructed and applied substantially as and for the purpose described.

E, D. NORTON.
